Koto traveled 5,000 meters north from her house with an average velocity of 4.5 m/s. What was the time of her trip? (There are 60 seconds in 1 minute.)

18.5

Step-by-step explanation:

took the test on edg.

18.5 minutes

Step-by-step explanation:

divide 5000 m/ 4.5 m/s = 1,111 seconds

1,111/60= 18.5 min

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

x/3-10=8

x/3=18

x=48
